Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, in particular to an industrial wastewater treatment device. Background Art

[0002] Industrial wastewater includes production wastewater and sewage. There are many types of industrial wastewater with complex components. For example, electrolytic salt wastewater contains mercury, heavy metal smelting wastewater contains lead, cadmium and other metals, electroplating wastewater contains cyanide, chromium and other heavy metals, petroleum refining wastewater contains phenol, and pesticide manufacturing wastewater contains various pesticides. Since industrial wastewater often contains a variety of toxic substances, polluting the environment and posing a great threat to human health, it is necessary to develop comprehensive utilization and turn harm into benefit. According to the composition and concentration of pollutants in the wastewater, appropriate purification measures must be taken before it can be discharged. Existing industrial wastewater treatment equipment is unable to recycle magnetic metals such as iron filings in the wastewater during treatment, resulting in a large waste of resources. Furthermore, when discharged, the iron filings are harmful heavy metals, polluting the environment.

[0003] The prior art discloses an industrial wastewater treatment device (publication number: CN219897369U), which includes a first treatment tank and a second treatment tank. A first pipe is provided on the left side of the first treatment tank, a first filter is provided inside the first treatment tank and near the left side, and an iron chip removal device is provided on the right side of the first filter. A filtering device is provided inside the second treatment tank and near the right side, and a third pipe is provided on the right side of the second treatment tank. Activated carbon is provided on the right side of the first non-woven fabric, and a second non-woven fabric is provided on the right side of the activated carbon. During use, iron chips in the wastewater will be directly adsorbed by the iron chip removal device.

[0004] However, the above technical solutions and the prior art still have the following defects:

[0005] During use of the utility model, the entire iron chip removal device is manually lifted, a trash can is found and the iron chip removal device is placed on top, and the strong magnet is lifted by the second handle. The iron chips will move upward and the baffle can block them all. After the strong magnet is removed, the iron chips will naturally fall into the trash can. However, since the wastewater treatment device continues to operate for a long time, the iron chips need to be cleaned regularly and multiple times, which results in the need for manual repeated disassembly and cleaning operations when cleaning the iron chips on the iron chip removal device, which increases labor intensity and the time of downtime caused by disassembly and cleaning, thereby reducing work efficiency.

[0027] The discharge port 13 on the other side of the first processing box 1 is connected and fixed to the feed port 14 on one side of the collecting box 2 through the connecting cavity 12. A cleaning mechanism 15 is provided inside the collecting box 2. The cleaning mechanism 15 is used to automatically clean and collect the iron filings adsorbed on the adsorption plate 7 to improve work efficiency.

[0028] A positioning frame 20 is fixedly installed on the top of the inner cavity of the first processing box 1, and positioning grooves 23 are provided at the four corners of the positioning frame 20. The positioning grooves 23 are adapted to the positioning posts 22 arranged at the bottom of the mesh frame 21. A first filter screen 6 is fixedly installed on the inner side of the mesh frame 21. The first filter screen 6 is conical, and hanging rings 24 are fixedly installed in the center of both sides of the mesh frame 21. By setting the positioning frame 20, the positioning posts 22 and the positioning grooves 23, the first filter screen 6 can be easily disassembled and cleaned.

[0029] A cover plate 10 is fixedly mounted on the front end of the strong magnet 9 . The cover plate 10 is engaged with the first mounting cavity 8 , and a first handle 11 is provided on the outer side of the cover plate 10 .

[0030] The cleaning mechanism 15 includes an electric push rod 151, a sealing plate 152, a connecting rod 153 and a scraper 154. The electric push rod 151 is fixedly installed on the other side of the collecting box 2, and the output end of the electric push rod 151 is fixedly connected to the center of the sealing plate 152. The sealing plate 152 is adapted to the discharge port 13, and the center of the sealing plate 152 is fixedly connected to the center of the scraper 154 arranged on the top surface of the adsorption plate 7 through the connecting rod 153. The bottom surface of the scraper 154 is slidably connected to the top surface of the adsorption plate 7.

[0031] The cleaning mechanism 15 also includes a second installation cavity 155, a collection box 156, a second handle 157 and a slide rod 158. The second installation cavity 155 is opened on the front side of the collection box 2, and the collection box 156 is slidably installed in the second installation cavity 155. The collection box 156 is used to collect iron filings, and the second handle 157 is fixedly installed on the front side of the collection box 156. The slide rod 158 is fixedly installed at both ends of the sealing plate 152, and the slide rod 158 is slidably connected to the inside of the collection box 2.

[0032] A guide plate 16 is provided at the feed port 14 on one side of the collecting box 2. The guide plate 16 is provided on the upper part of the collecting box 156. By providing the guide plate 16, the iron filings can be accurately put into the collecting box 156 at the bottom.

[0033] In this embodiment, by setting a collection box 2, a connecting cavity 12, a discharge port 13, a feed port 14 and a cleaning mechanism 15, the cleaning mechanism 15 is used to automatically and centrally process the iron filings adsorbed in the first processing box 1 into the collection box 2, thereby realizing automatic cleaning and improving work efficiency. By driving the electric push rod 151, its output end drives the sealing plate 152, the connecting rod 153 and the scraper 154 to move left and right. When the output end of the electric push rod 151 contracts inward, it directly drives the sealing plate 152 and the scraper 154 to move to the left, so that the scraper 154 is attached to the top surface of the adsorption plate 7. It moves, so that the iron filings adsorbed on it are scraped to the left into the collection box 156 at the bottom of the collection box 2 during the movement. After the iron filings are scraped off, the output end of the electric push rod 151 is driven forward to push the sealing plate 152 and the scraper 154 back to their original positions. The discharge port 13 on the other side of the first processing box 1 is sealed by the sealing plate 152. The second handle 157 is directly pulled to pull the collection box 156 out of the second installation cavity 155, and the collected iron filings can be processed. The operation process is simple and convenient, which effectively reduces the operation time of iron filing processing, thereby improving work efficiency.

[0034] Working principle: First, the wastewater is transported to the first treatment box 1 through the water inlet 5, and the larger impurities in the wastewater are filtered through the first filter screen 6. The filtered wastewater falls directly onto the adsorption plate 7, and the iron filings in the wastewater are adsorbed onto the adsorption plate 7 through the action of the strong magnet 9 at the bottom of the adsorption plate 7. Then the wastewater is sent to the second treatment box 3 through the filter assembly through the servo pump 17 for further filtration. The output end of the electric push rod 151 is driven to retract inward, and the iron filings adsorbed on the adsorption plate 7 are scraped to the left by the scraper 154. When scraped into the connecting cavity 12, due to the reduction and loss of magnetic force, the iron filings can be scraped into the collection box 156 in the collection box 2. During the operation of the cleaning mechanism 15, the wastewater can be blocked from entering the first treatment box 1 for a short time. After the iron filings are processed, the valve is opened to allow the wastewater to enter. The operation is relatively automatic and fast, and does not require a long processing time, thereby ensuring work efficiency.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
